I have a 1991 Chevy Cheyenne, 4.3 L engine, that has the brake light flashing. Not sure what could be causing this. Is there a computer on this model truck? Is this a diagnostic code or something? It mainly flashes while driving. Thanks for the advice.

Hi there,

Check the adjustment of the brake light switch, or replace if adjustment is ok.
